To all whom it may concern.-

Beit known that I, W LTER E. CnAUssEN, acitizen of the United States, residing at Hartford, in the county/of Hartford. and State of Connecticut, have invented certain new and useful Improvements in Feeding IvIechanism, of which the following is a specification. I p

This invention relates to feeding mechanism, and the same may be employed with advantage in many different connections or as part of machines of various types; it is of especial utility, however, when incorporated in or constituting a portion of a machine for making aper cups, and in this particular use is a apted to supply blanks one at a time from a pile or stack to cupforming mechanism of any desirable nature.

Among the objects of. the invention are the provision of mechanism of the character noted, which is simply in construction, effective in action, and by which blanks can be accurately and rapidly furnished to any part designed to operate upon the same.

The invention possesses other features of novelty and advantage, which with the foregoing will be outlined at length in the following description, wherein I will set forth in detail that one of the several forms of embodiment of the invention which I have selected for illustration in the drawings accompanying and forming part ofthe present specification, this disclosure being primarily provided to enable those skilled in the art to practise the same. It will be understood therefore that I do not restrict myself to such disclosure; I may depart therefrom in several res cots within the scope of my invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a top plan view of feeding mechanism involv-' ing my invention. Fig. 2 is a side elevation of the same partly insection. Fig. 3 is a cross section on the line 3-3 of Fig.- 2 looking in the direction of'the arrow. Fig. 4 is a front elevation. Fig. 5 is a transverse section on the line 5-5 of Fig; 2. Fig. 6 is a section on the line 6-6 of Fig. 5. Fig. 7 is a detail view of caring hereinafter more particularly described.

Like characters refer to like parts throughout the several figures.

It is not materialwhat is fed by meeha nism involving" the present invention, al

though as I have already intimated said mechanism is of peculiar utility when embodied in a paper cup machine, being employed in this case to supply'blanks one at a time, from a pile or stackto cup-forming mechanism. The blanks may vary as to shape, although in thepresent instance they are circular or consist of paper disks. When of this form they. are supplied to plaiting mechanism which constitutes the subject matter 'in-part, of a separate copending application filed August 19, 1912, Serial No. 715,790. As a matter of fact I prefer to duplicate the plaiting or other cup-forming mechanisms.- From this it will be clear that it is not necessary that the cup should be former by plaiting. I

The different parts of the machine may be supported by any suitable framework, that shown being denoted in a general way by 10. The blank support may be of any suitable nature, that shown being denoted by 12 and being disposed as represented, at an upward, forward inclination and being provided with several upstanding rods or stanchions 13, to receive and confine the pile of blanks, there being in the organization illustrated'three of such rods,- two of which engage the sides of the pile of blanks at substantially diametrically opposite points,

while the third one engages the rear of said pile. This practically presents a skeleton carrier for the pile of blanks, open at the.

forward side, the opening at such point permitting the free removal of the blanks which in the organization shown are positively removed one by one from the stack, at the bottom.- The support or shelf 12 as illustrated is approximately rectangular and the forward, upper side of the pile or stack of blanks extends forward beyond or overhan the front end of said support to facilitate t e removal of the blanks which as will hereinafter appear are bent downward upon themselvesone at a time to initiate the withdrawing or separating movement and to insure the proper folding or flexing of the blanks, the front edge of the support or shelf 12 is Sll'OYiVIl as beveled on a downward outward an e. i

n connection with-the blanks there is a positive removing or withdrawing device, and although this may vary in nature, one of pneumat 0 type satisfactorily answers my noted in a general way b 14. This blankwithdrawing member inc udes in its makeup a tubular shaft 15 supported for rocking motion by suitable-bearings on the frame work 10 and having'between its ends the crank or forwardly bowed portion 16, provided with an upwardly curved or arcuate hollow or tubular finger 17 adapted to pick the sheets or blanks from the stack in succession. In the present case the axis of motion' of said shaft 15 intersects the front edge of the support or shelf 12. It should be stated that accidental bending downward of the stack of blanks where the same overhangs the front of the support or shaft 12, is prevented in some positive manner, and for this purpose the projection 18 may be provided, this projection engaging under the front portion of the stack for such purpose. This detent 18 depends from the yoke 19, the ends of which are supported in suitable hearings on the'framework of the machine.

The blank withdrawing or removing device 14 as will hereinafter appear is intermittently oscillated, the tip of the picking finger 17 being normall free or away from the lowermost blank 0 the stack. 0n the.

advancing movement of the withdrawing member 14 said tip or free end of the finger is brought into contact with the lowermost blank of the pile, and simultaneously the air is exhausted from the said withdrawing device 14 so that the forward portion of the lowermost sheet on the retractive or downward movement of the finger 17 is drawn by suction in a downward 'direction, said sheet being flexed at the front edge of the shelf or support 12 and being separated from the detent 18; The sheet when the free portion thereof is thus pulled down, is received between a pair of gripper and feed rolls.of novel construction and which will be hereinafter more particularly described.

The sides of the framework support the power shaft 20 which may be rotated in any desirable manner, and from which a pump or equivalent apparatus for exhausting the air from the blank withdrawing device 14 may be driven. This pump may be of any suitable character; as a matter of fact any other means may be provided for the same purpose. The pump shown comprises in its make-up the cylinder 21 and the piston 22 therein the stem of the piston having a fork 23 straddling and guided by the power shaft 20. To reciprocate the piston 22 the cam 24 rotative with the continuously operable power shaft 20, may be provided, said cam aving a side groove 25 to recelve the stud 26 on the stem of the piston 22, this providing a simple means for reciprocating said piston. It should benoted that the parts are so proportioned that the suction stroke of .the piston 22 will commence just about the time the picker finger 17 comes in contact with the lowermost blank and will continue until the blank operated upon by said picker finger has been grasped by the gripping and feed rolls which I will hereinafter more particularly describe. The

pump cylinder 21 is connected by piping as 27 with one end of the shaft 15.

To oscillate the shaft 15 and therefore impart a corresponding movement to t e picker finger 17 any suitable means may be provided, although in the present case one stroke is effected by cam means and the opposite by spring means, the cam for this purpose being denoted by 28, being rotative with the power shaft 20, and being adapted to engage against the projection 29 on the crank arm 30 rigid with the inner end of the shaft 15. Encircling the shaft near said end is a coiled spring 31, one end of the spring being connected to the shaft and the other to a fixed 'pin 32 on the framework 10. The cant 28 acting against the stud or projection 29 tends through the described parts, to impart 'a downward movement to the crank arm 30 and therefore to the picker finger 17 during which the spring 31 is tensioned, so that when the releasing portion of the cam frees the projection or stud 29, opposite movement'of the crank arm and picker finger can be accomplished by the reaction of said spring.

The sheets or blanks when successively pulled down as described are presented to provide for the swing of the picker finger 17. The apertures of the two rollers can be conveniently secured by making said rollers in sections and the picker finger 17 operates in the said apertures. The lower roller 35 is fixed to the main shaft 20, while the shaft of the upper roller .36, is formed in sections 37 and 37 supported for rotation respectively by the ends of the yoke 19 which effectually maintains said shaft sections in axial alinement. The main shaft 20 has fixed to it the spur -gears 38 in mesh with pinions 39 on the shaft sections 37 and 37, this presenting a simple means for simultaneously rotating the two rollers 35 and 36. Said rollers 35 and 36'are shown of different diameters, the upper one 36 being in the present case smaller than the lower, although this is not essential.

The intermediate, slotted -or. -apertured cut away portion 40, the front edge thereof blanks up to a certain point.

35, the two rollers can seize and wholly remove the sheet from the stack and enter the same into the bight of a. second pair of,

rollers 42 and 43 operable as hereinafter set forth, which advance the same onto a carrier such as that denoted in a general way by 47. One of the spur gears 38 is.

in mesh with the widefaced pinion 44 mounted as an idler on the framework and which in turn meshes with the spurgear 45- meshing in turn with the similar gear 46, said shafts of the feed rollers 42 and 43 to simultaneously rotate the same. Said carrier 47 includes 'in its make-up, companion endless bands or belts 48 which act as one of their functions to simultaneousl advance the 7 Each belt also acts to transfer power as will hereinafter appear. The inner portions of the two 'belts 48 are fitted around a drum 49 .com-

plemental to the pressure drum 50 located directly over the same, the upper drum hearing against the inner portions of the two belts. Fastened to the shaft. of the lower drum 49 is a spur gear 49. in mesh with the wide-facedpinion 44 and'in mesh with the spur gear 49 is a like spur'gear 50 fastened to the-shaft ofthe upper drum 50 and by which the two drums can be r0- tated in unison.

The belts between their ends are bent downward to provide openings as will hereinafter appear, for the assage of a feed orpusher member which is preferably oscillatory, and as will also hereinafter appear, said belts are extended outwardly at the place where the pusher meniber operates.

I will describe the mounting of one belt 48 which will apply practically t0 the other.

The upper run of the belt 48 in the foreground in Fig. 2 extends dver the guide sheave 51 and downward around the guide sheave 52 and then upward around the guide sheave 53, the guide sheaves 51 and 53 being virtually horizontally alined, while the guide sheave 52 is below the two other sheaves, the three being ractically triangularly arranged so as to orm as it were a triangular opening 48 in which thefeed member 54 can operate. The belt 48 after leaving the V sheave 53 extends downward around the forming mechanism, although the same 'is gears 45 and 46 being fixed to theagain inward around the sheave 57, the two sheaves 56 and 57 being rotative about vertical axes. The sheaves 51 and 52,- 53,

.55 and 57 v are supported by a bracket 58 which may be attachedto the framework 10 or supported one column as 59 extending to the floor, the sheave 56 of large diameter being supported by a side bracket 60.

Associated with each sheave 56 is cup not shown herein. This cup-forming mechanism may be of any suitable character, for

example of the kind which form by plaiting, the circular blanks or -disks,.into cup shape. As already intimated, however, the cupforming or shaping mechanism constitutes no part of the present invention, for which reason it is not referred to more particularly herein. V

- The feed or pusher member 54 to which reference has been made as shown is fastened to the rock shaft 61 carried upon the 7 arm 62 Sui-mounting the post or standard 63 on the framework 10. To the outer or forward end of the rock shaft 61 is fastened the rocker 64 to which is jointed the rod 65 adapted to be power-operated in some suitable manner, to oscillate or swing the feed or pusher member 54 which when in its mid position, stands approximately centrally between the feed portions of the two belts 48 and which, as will be clear has a movement alternately through the triangular open- 'ings '48 in the two belts 48. The belts 48 jointly advance the blanksor disks up to the feed or pusher member 54 and as the said pusher member oscillates,'it pushes the blanks alternately in opposite directions, the first blank operated upon'being moved for instance toward one sheave or equivalent support 56 and the ensuing one toward the complementary sheave 'or support 56, this action bein continued as long as the blanks are fed an the machine is in motion.

To guide the blanks onto the respective rotary supports 56, the arallel guide members 66 may be provi ed, these members being fastened to the stationary shafts of the two pairs .of upper guide sheaves 51 and 53 and extending outward therefrom. The 5 outer ends of the guidemembers 66 extend short of the rotary supports 56.
